Description

Technical Field

[0001] This utility model relates to fixtures, and more specifically, to a tooling fixture for welding batteries. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for machining or inspection; it is also called a clamp. In a broader sense, any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process can be called a fixture. A fixture typically consists of positioning elements (which determine the correct position of the workpiece within the fixture), clamping devices, tool setting and guiding elements (which determine the relative position of the tool and the workpiece or guide the tool direction), indexing devices (which allow the workpiece to complete machining at several stations in a single setup; there are rotary indexing devices and linear indexing devices), connecting elements, and the fixture body (fixture base).

[0003] The Chinese patent announcement CN221247558U discloses an adjustable lithium battery welding fixture, the key technical features of which are: an adjustable base, a movable seat slidably connected to the top of the adjustable base, an adjustable cylinder fixedly connected to the top of the movable seat, a first telescopic rod fixedly connected to the output end of the adjustable cylinder, and a top plate fixedly connected to the top of the first telescopic rod.

[0004] In the above technical solution, both sides of the upper and lower surfaces of the lithium battery are fixed, which can prevent slippage during flipping. The movable seat can be moved to adjust its position, which can improve the adjustment range during lithium battery processing. However, it can only fix a single material, resulting in low production efficiency.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tooling fixture for welding batteries.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tooling fixture for welding batteries, comprising a base, wherein a mounting frame is bolted to the base, characterized in that: a transport base plate is slidably connected to the base, a placement base plate is bolted to the transport base plate, the placement base plate is provided with a plurality of placement slots, and the placement base plate is also provided with a plurality of positioning slots, the number of positioning slots and placement slots corresponding to the number of placement slots, a lifting connecting assembly is slidably connected to the mounting frame, the lifting connecting assembly is provided with a welding component for welding materials, and a cover plate for covering the placement base plate is provided below the welding component.

[0008] By adopting the above technical solution: the material is placed in the placement trough and precisely positioned by the positioning slot.

[0014] The present invention is further configured such that: a telescopic rod is provided at the bottom of the cover plate, and a telescopic sleeve is elastically connected to the bottom of the telescopic rod, and the telescopic sleeve is fixedly connected to the surface of the base.

[0015] The present invention has the following advantages: 1. The transport base plate can slide along the base to the welding station, and after welding is completed, it returns to the initial position, which makes it easy to remove the workpiece and load it into the next batch, thereby improving production efficiency.

[0016] 2. By combining the placement slot and the positioning slot, materials can be accurately positioned; the placement slot is equipped with a positioning spring and a positioning plate, which can adjust the space according to the size of the material to prevent the material from shaking or shifting during transportation and processing.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] like Figure 1 and Figure 5As shown, a tooling fixture for welding batteries includes a base 1, a mounting frame 2 bolted to the base 1, a transport base plate 3 slidably connected to the base 1, a placement base plate 4 bolted to the transport base plate 3, a plurality of placement slots 5 and a plurality of positioning slots 6 on the placement base plate 4, the number of positioning slots 6 corresponding to the number of placement slots 5, a lifting connection assembly slidably connected to the mounting frame 2, a welding component 7 for welding materials on the lifting connection assembly, and a cover plate 8 for covering the placement base plate 4 below the welding component 7.

[0027] In use, the battery to be welded is placed in the placement slot 5 and precisely positioned by the positioning slot 6. Then, the transport base plate 3 slides along the base 1 to the welding station. The lifting connecting assembly moves the welding part 7 downward, while the cover plate 8 covers the placement base plate 4 to prevent foreign objects from entering or parts from shifting during the welding process. The welding part 7 performs precise welding on the battery. After completion, the lifting connecting assembly resets, and the transport base plate 3 returns to its initial position, facilitating the removal of the workpiece and loading into the next batch, thus achieving continuous operation. The base 1 and the mounting frame 2 provide support for their respective components. The transport base plate 3, through a sliding connection with the base 1, enables the transfer of the placement base plate 4 and the materials it stores. Several placement slots 5 and positioning slots 6 work together to position the materials. At the same time, multiple materials can be accommodated at once, improving processing efficiency. The welding part 7 is a welding head or welding gun in the prior art.

[0028] like Figures 1 to 3 As shown, a transport slide rail 9 is fixedly connected to the surface of the base 1, and a transport slider 10 is slidably connected to the transport slide rail 9. The transport slider 10 is bolted to the transport base plate 3. The transport slide rail 9 and the transport slider 10 provide guidance and support for the sliding of the transport base plate 3, so that the transport slide plate and its components can slide accordingly to realize the transfer and transportation of materials.

[0029] like Figure 5 As shown, each placement slot 5 is equipped with a positioning spring 11, and the positioning spring 11 is fixedly connected to a positioning plate 12. The positioning spring 11 exerts a force on the positioning plate 12, which increases or decreases the space in the placement slot 5 to accommodate materials of different sizes. When the material is placed in the placement slot 5, the material exerts a force on the positioning plate 12, and the positioning spring 11 is compressed accordingly, so that the other end of the material is inserted into the positioning slot 6. The positioning slot 6 and the positioning plate 12 abut against the two ends of the material, so that the material will not shake or shift during transportation and processing.

[0030] like Figures 1 to 3As shown, the lifting connection assembly includes a lifting cylinder 13, a connecting plate 14 is provided on the piston rod of the lifting cylinder 13, the connecting plate 14 is connected to the welded part 7, a translation slider 15 is bolted to one side of the lifting cylinder 13, the translation slider 15 is slidably connected to a translation rail 16, the translation rail 16 is fixedly connected to the mounting bracket 2, a lifting seat 17 is provided on the top of the lifting cylinder 13, and a translation drive assembly is provided on the lifting seat 17; the translation drive assembly includes a translation motor 18, a translation screw 19 is provided on the output shaft of the translation motor 18, a translation connecting block 20 is provided on the translation screw 19, and the translation connecting block 20 is bolted to the lifting seat 17.

[0031] The translation motor 18 is the power source. The output shaft of the translation motor 18 drives the translation screw 19 to rotate. The translation connecting block 20 converts the rotational motion of the translation screw 19 into linear motion. The translation connecting block 20 moves horizontally. The displacement of the translation connecting block 20 drives the lifting seat 17 to move. The displacement of the lifting seat 17 can drive the lifting cylinder 13 to move. When the lifting cylinder 13 moves to directly above the placement base plate 4, the piston rod of the lifting cylinder 13 drives the connecting plate 14 and the welded part 7 to descend. The welded part 7 performs corresponding processing on the material.

[0032] like Figure 3 and Figure 4 As shown, the translation screw 19 is driven by a horizontal shaft 21, and a first gear 22 is driven by the horizontal shaft 21. The first gear 22 is driven by a second gear 23. The mounting bracket 2 has a gear groove 24 for the first gear 22 and the second gear 23 to rotate. The second gear 23 is driven by a lifting screw 25, and an abutment block 26 is rotatably connected to the lifting screw 25. The bottom of the abutment block 26 abuts against the top of the cover plate 8.

[0033] While the translation motor 18 rotates and drives the lifting cylinder 13 to move horizontally, the horizontal shaft 21 drives the first gear 22 to rotate. The first gear 22 and the second gear 23 are both bevel gears. The first gear 22 and the second gear 23 mesh with each other and drive the second gear 23 to rotate. The rotation of the second gear 23 can drive the lifting screw 25 to rotate, and the abutment block 26 can move up and down, so that the abutment block 26 can abut against the cover plate 8, and the cover plate 8 can stably cover the surface of the base plate 4.

[0034] like Figures 1 to 3 As shown, a telescopic rod 27 is provided at the bottom of the cover plate 8, and a telescopic sleeve 28 is elastically connected to the bottom of the telescopic rod 27. The telescopic sleeve 28 is fixedly connected to the surface of the base 1. The telescopic rod 27 and the telescopic sleeve 28 can provide corresponding support for the cover plate 8. At the same time, when the base plate 4 is placed and the cover plate 8 is not needed to be closed, the cover plate 8 can also be reset accordingly.

[0035] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
